3 To selectively remove vertices on a 3D polyline, enter the following criteria
under Weeding Factors:
n
Maximum Horizontal distance
n
Maximum Horizontal deflection angle
n
Maximum Grade Change (percent)
4 Select or clear the Include Grade Change in Weeding factors check box.
5 Select or clear the Erase Existing 3D Polylines check box.
The program applies the weeding factors on the set of 3D polylines selected and
highlights the removed vertices with a temporary red + or x. The original
entities are erased. The command line displays the total number of original
vertices, the total number of vertices removed, and the number of new vertices.
Grading Settings
Grading objects are created using the settings you specify for the footprint,
targets, slopes, corners, accuracy, and appearance. There are three different
methods of establishing these settings. The method you choose to access the
settings depends on whether you are creating a new grading object or editing an
existing grading object.
n
If you are creating a new grading object, then you can use the Grading
Wizard or the Apply Grading command. Before you use the Apply Grading
command, use the Settings command to set up the initial settings.
n
If you are editing a grading object, then you can use the Grading Properties
command to change the settings.
The grading settings, grading properties, and the Grading Wizard all contain the
same settings. However, some areas of the grading settings dialog box display
information only after you have created a grading object.
In this manual, each group of settings is described in its own topic. Because you
can access these settings from multiple commands, the first step in each topic
describes how to access these three commands. In addition, some methods
require less steps than others, and the manual indicates which steps to skip in
these instances.
